[The scaphoid fracture : Between pseudoarthrosis and possible anatomical variance]. / Die Skaphoidfraktur : Zwischen Pseudarthrose und möglicher anatomischer Varianz.

The diagnosis of a scaphoid fracture, especially in the differentiation of a fresh fracture, the nonunion or a possible anatomical norm variant, can be difficult. We report on two patients who presented with stress-related, radiocarpal pain in our department. In both cases, radiological abnormalities were observed in the scaphoideal area, with a scaphoideum bipartitum on both sides, as well as an approximately 25-year-old scaphoid pseudarthrosis.

Lancefield group G Streptococcus dysgalactiae subsp. equisimilis: an unusual aetiology of perianal streptococcal dermatitis acquired from heterosexual oral-anal intercourse.

Perianal streptococcal dermatitis (PSD) is an uncommon superficial cutaneous infection of the perianal area, almost exclusively described in children and mainly caused by group A streptococci. We report here a case of PSD caused by Streptococcus dysgalactiae subsp. equisimilis, Lancefield group G, in an adult man due to heterosexual oral-anal sexual contact.

Histopathology based cancer pattern in Mymensingh region of Bangladesh.

To our knowledge, population-based published data regarding the cancer profile in Mymensingh region of Bangladesh is not available. This study was designed to provide information regarding the frequencies of cancers through sample data retrieved from histopathology (surgical pathology) laboratory based cancer registry from two laboratories in Mymensingh. All malignant tumours recorded in 2006 in the register of pathology laboratory of Mymensingh Medical College and one private pathology laboratory in Mymensingh town were taken as sample data for analysis in terms of age groups, gender and types of cancer with relation to site. A total of 470 cases diagnosed as cancer were found in the register, of which males were 249(53%) and females were 221(47%) with male to female ratio 1.2: 1. Highest numbers of cases were found in the age group of 51-60 years. In male group frequency of malignant tumours was found in the age group of 51-60 years and the female group it is 41-50 years. Top five sites of cancer, irrespective of sex, were of stomach, uterine cervix, colo-rectum, lymph nodes and breast. According to decreasing order of frequency, in the males, the top five cancers were of stomach, lymph node, oesophagus, urinary bladder and colo-rectum. In the female groups these were of uterine cervix, breast, ovary, colo-rectum and stomach. Cancer cases in the age group of 51-60 years were significantly higher in males than in females (p<0.001). The commonest cancers in males and females were of stomach and cervix, respectively. As the analysis was based only on surgical specimens, the exact incidence of cancer of lung and liver could not be evaluated. Because, majorities of the malignancies in these organs are diagnosed mainly on cytological examination. Population-based cancer registry should be maintained to explore the exact patterns of cancer in the study region. Cervical cancer screening program and eradication of H. pylori infection program may be helpful for the reduction of incidence of cancer in this region.

Moraxella catarrhalis associated with acute urethritis imitating gonorrhoea acquired by oral-genital contact.

A case of heterosexual transmission of Moraxella catarrhalis by fellatio, which resulted in acute purulent urethritis mimicking gonorrhoea in the male partner, is described. In male patients with urethritis due to M. catarrhalis, orogenital contact with a sexual partner carrying the organism in his/her oropharynx is the probable route of transmission.

Histopathological analysis of hysterectomy specimens.

The objective of this study was to explore the histopathological findings and the rate of removal of ovaries in hysterectomy specimens. This study took into account 328 hysterectomy specimens examined in the Department of Pathology, Mymensingh Medical College and in one private Pathology Laboratory in Mymensingh town from March to August, 2005. Formalin fixed paraffin embedded tissue sections stained with haematoxylin and eosin were examined under light microscope. Patients' age, parts of uterus examined and their histopathological findings were retrieved from laboratory records. The common histopathological findings were: chronic cervicitis (87.80%), leiomyoma (17.07%), uterine prolapse (16.72%), adenomyosis (3.96), non-specific endometritis (3.35%), squamous cell carcinoma of cervix (2.44%), endometrial polyp (2.44%), serous cystadenoma of ovary (2.44%) and endometrial hyperplasia (1.83%). Some of the specimens show more than one lesions in the body of uterus, of which coexistence of adenomyosis and leiomyoma was the most common. Neoplastic lesions in cervix were 4.27%, in body 16.92% and in ovaries 5.06%. Malignant neoplasms were found in cervix 71.43%, in uterine corpus 3.03% and in ovaries 25%. Ovaries of both sides were removed in 48.17% of total cases. Their median age was 45 years, lowest age 23 years and maximum age was 82. The rate of removal of both ovaries was found to be increasing with the increase of age. Only one case was found to be subtotal hysterectomy and others were total hysterectomy. The present study revealed that the most common histopathological cause of hysterectomy is chronic cervicitis. Most common neoplastic cause of hysterectomy is leiomyoma. The rationalities and the possible after effect of hysterectomy in sexual functions and other physiological impairment should be followed up.

Four near-isogenic lines of cotton with different genes for bacterial blight resistance.

ABSTRACT The development and genetic characterization of four near-isogenic lines (NILs) of cotton (Gossypium hirsutum) is described herein. Each line contains a single, but different, gene for resistance to bacterial blight caused by Xanthomonas campestris pv. malvacearum. The lines were derived using at least six backcrosses to the susceptible recurrent parent 'Acala 44', followed by single plant-progeny row selection for uniformity. The NILs are homozygous for the B(2), B(4), B(In), or b(7) genes and are designated as AcB(2), AcB(4), AcB(In), and Acb(7), respectively. In the 'Acala 44' background, B(2), B(4), and B(In) are partially dominant genes; b(7) is partially recessive. Relative strengths of resistance conferred by those genes toward race 1 of the pathogen were B(4) b(7)>B(In) B(2). B(4), B(In), and b(7) each conferred resistance toward X. campestris pv. malvacearum carrying a single avirulence gene, whereas B(2) was less specific.

Changes in the electrical activity of the stomach after partial resection of the pancreas and occlusion of the pancreatic duct.

The electrical activity of the stomach and duodenum of six mongrel dogs was studied under chronic conditions after partial resection of the pancreas and occlusion of the pancreatic duct. Changes in the electrical activity were observed only in the stomach, manifested in the form of groups of slow potentials with accelerated rhythm (over 7 cpm--tachygastria) or delayed rhythm (below 3 cpm--bradygastria). A definite dynamics was observed in the appearance and development of rhythmic disorganization. The duration of the groups of slow potentials with abnormal rhythm increased 10-12 days after surgery. Radioimmunological studies showed a postoperative increase in the glucagon level, paralleled by a decrease in the content of the C-peptide and insulin in the blood plasma. Influsion with insulin (0.5 IU i.v.) regulates the disorganized antral rhythm. The dysbalance in the insulin/glucagon ratio in the blood serum is assumed to be the probable mechanism of the rhythmic disturbances.
